Troubleshooting

Even though the MU5 is exceptionally easy to use, it may occasionally not
function as you expect it to. If that happens, check the possible problems and
solutions below before assuming that the instrument is faulty.
Problem
No power.
No sound.
Possible Cause and Solution
• If you are using an AC adaptor, check that the
adaptor is properly plugged into both the AC
outlet and the MU5. (See page 14.)
• If you are using batteries, check that a fresh set
of batteries are properly installed in the battery
compartment. (See page 15.)
• Check that the side panel volume control is set
to an appropriate level. (See page 10.)
• Check that other volume-related parameters are
set to appropriate levels. (See Velocity, page
34, and Volume, page 39.)
• Check that the Parts being played are properly
turned on. (See page 26.)
• Check the Mute and Solo settings. (See page
29.) If a Part is being muted, or an empty Part
is being soloed, you may not get any sound.
